An evaporative material system and method of manufacture

Abstract

A method of manufacturing corrugated paper or similar evaporative media incorporating a liquid spreader block section on a liquid entry side of a core block of media, wherein an additional member is fitted to the core block opposite the spreader block section such that separation of adjacent sheets of corrugated paper within the core block is resisted by the combined presence of the spreader block and the additional member. The additional member is preferably of the same or similar material to that of the spreader block or the main block.

1 . A method of manufacturing corrugated paper or similar evaporative media incorporating a liquid spreader block section on a liquid entry side of a core block of media, wherein an additional member is fitted to the core block opposite the spreader block section such that separation of adjacent sheets of corrugated paper within the core block is resisted by the combined presence of the spreader block and the additional member.  
   
   
       2 . A method as claimed in  claim 1 , wherein said additional member is of the same or similar material to that of the spreader block.  
   
   
       3 . A method as claimed in  claim 1 , wherein the additional member is of the same or similar material to that of the core block.  
   
   
       4 . A method as claimed in any one of the preceding claims, wherein the additional member is a block of the core material adhesively fixed to the core block.  
   
   
       5 . A method as claimed in any one of the preceding claims, wherein the airflow passages in the additional member are aligned orthogonally to airflow passages in the core block.  
   
   
       6 . A method as claimed in  claim 1 , wherein the additional member is a flat sheet adhered to the core block.  
   
   
       7 . A method as claimed in  claim 1 , wherein the additional member is a member shaped to be retained in contact with a perimeter of the core block on a water exit side of the core block.  
   
   
       8 . A block of corrugated paper or similar evaporative media when formed by a method of any one of the preceding claims  
   
   
       9 . A method of manufacturing a corrugated paper or similar evaporative media substantially as hereinbefore described with reference to  FIG. 4  of the accompanying drawings.  
   
   
       10 . A block of corrugated paper or similar evaporative media substantially as hereinbefore described with reference to  FIG. 4  of the accompanying drawings.
